#### Explanation:

First, let's call "a number": $n$

Then, for "four times a number" we can write:

$4 \times n$ or $4 \cdot n$ or $4 n$

This expression "decreased by one" means to subtract one so we can write:

$4 n - 1$

Now, this expression "is -29" means it equals -29 so we can write:

$4 n - 1 = - 29$
